Can I train BJJ with glasses or contact lenses?

Glasses are a definite safety hazard on the BJJ mat and should always be removed before training. Contact lenses work well for most people during technique instruction and drilling. During rolling, you may occasionally lose a lens, so keeping a backup pair in your bag is wise. Some practitioners choose to train without any vision correction since most of BJJ happens in close quarters where you can feel rather than see what is happening. If you rely heavily on your vision, daily disposable contacts are the most practical option because losing one is less costly. LASIK or other vision correction surgery is popular among BJJ practitioners who want to eliminate the hassle entirely. Store your glasses in a hard case in your gym bag to keep them safe during class.
